Over the last decade, everyone has been harping on about the beauty benefits of olive oil, but the truth is this kitchen staple has been used on the body since ancient times (thank you, Cleopatra).

Naturally, olive oil is packed with anti-ageing antioxidants and hydrating squalene, making it superb for hair, skin, and nails. Just like coconut oil, it's an essential in any DIY beauty maven's kit.

Check out the 12 most unexpected beauty uses for olive oil:

1. Pre-shampoo hair treatment

Olive oil has been used as a hair treatment since ancient Egyptian times. First, warm olive oil in the microwave or under a hot water stream. Then apply generously to the ends of hair and scalp. Leave it in for up to 10 to 20 minutes, and then shampoo it out.

2. Lip scrub

Combine coarse sugar with a teaspoon of olive oil for a chapped-lip fix. You can also add a splash of lemon juice for added flavor and acidic exfoliating properties. This scrub is good enough to eat (literally) plus, you can expand the recipe for your whole body.

3. Eye makeup remover

We know what you're thinking - slathering olive oil all over your face would actually cause bigger problems and clog pores. But in actuality, the oil grabs on to other oil-based products (think: like attracts like), making it a great pre-cleansing step to remove stubborn eye makeup. Follow it up with warm water and a PH-balanced face wash.

4. Ear wax remedy

If you often have ear wax buildup, turn to olive oil to flush out the clog. For three or four nights, put a few drops into the ears before bed to help loosen excess wax.

5. Shine serum

There's no need to buy a separate hair product to impart shine on second-day strands. Just rub in a few drops of olive oil to flyaway ends after styling for an extra-glossy finish.

6. Shaving cream

Run out of shaving cream? Head to the kitchen, and slather legs with olive oil before applying the blade. You'll ward off razor burn and bumps with the help of this natural lubricant.

7. Antibacterial balm

If you're into taking an all-natural approach to medicine, you can whip up this DIY recipe for a Neosporin knockoff. It includes antibacterial olive oil along with lavender, calendula, and tea tree oil to ward off germs and scarring.

8. Cuticle conditioner

Want to grow longer, stronger nails? Use olive oil as your cuticle softener. Chef Giada de Laurentiis applies the oil to her hands as she cooks, and you can easily keep a little by the sink for post-sanitising moisture.

The best and most widespread use of olive oil is as an intense moisturiser. This product works great as an all-over treatment for extra-dry skin. Since it's natural, it's the ideal pick for eczema and more.

10. Diaper rash

There are very few products that are safe for both babies and adults. Olive oil is perfect for sensitive skin on a baby's bottom and as a moisturising remedy for cradle cap too.

11. Cracked heels

Split, rough heels need moisture to heal. After exfoliating with a pumice stone, apply olive oil to feet. Put on socks to lock in the hydrating treatment as you sleep.

12. Makeup brush cleaner

Cleaning your makeup brushes should be a monthly ritual. You can use a DIY cleanser that's two parts antibacterial soap and one part olive oil.
